Proposed model of the functions of V1 neurons. a During fast swimming, excitatory neurons (pink) provide strong phasic excitation to fast-swimming circuits (thick pink line). Excitatory neurons (pink) also provide moderate phasic excitation to fast-swimming circuits (thin pink line). Fast-type V1 neurons provide strong phasic inhibition to both of the circuits (thick blue lines). The strong phasic inhibition of fast-swimming circuits plays a role in frequency regulation. The strong phasic inhibition of slow-swimming circuits plays a role in shutting down the activities of the component neurons. b During slow swimming, excitatory neurons (pink) provide phasic excitation to slow-swimming circuits (pink line). Slow-type V1 neurons provide phasic inhibition to the circuit (blue line). The phasic inhibition plays a role in frequency regulation
